TECHNICAL FIELD

The present disclosure relates to the field of display technologies and, in particular, to an array substrate, a liquid crystal display panel, and an organic light emitting display panel.

BACKGROUND

In the field of display technologies, the most popular display technologies include a liquid crystal display technology and an organic light emitting diode display technology. A display panel is an important part for both of these two display technologies.

FIG. 1 is a schematic top view of a display panel in the related art. As shown in FIG. 1, a common display panel is divided into a display area 1 and a peripheral circuit area 2 surrounding the display area 1. Display panels for the two display technologies each include an array substrate, where a plurality of pixel units are arranged in the display area 1 of the array substrate, while corresponding driving circuits are arranged in the peripheral circuit area 2 of the array substrate to drive each of the pixel units.

The peripheral circuit area in which the driving circuits are located is a nonluminous area which forms a frame of the display panel, and a size of the frame of the display panel is determined by the size of the driving circuits. With increasing requirements of users for the display technology, a need for a frameless display also grows. However, this need cannot be satisfied because of the impact of the driving circuits in the related art.

SUMMARY

In view of this, embodiments of the disclosure provide an array substrate, a liquid crystal display panel, and an organic light emitting display panel.

An aspect of embodiments of the disclosure provide an array substrate, including:

-   -   a plurality of pixel units arranged in a plurality of rows and a         plurality of columns and divided into a plurality of pixel unit         groups each including n rows of pixel units, where n is equal to         or larger than 1; and     -   at least one driving circuit each disposed on a side of the         pixel unit group in a row direction;     -   where the at least one driving circuit interleaves with         neighboring preceding and succeeding pixel unit groups in a         column direction of the plurality of pixel units.

Another aspect of embodiments of the disclosure provide a liquid crystal display panel, including the above-described array substrate.

Yet another aspect of embodiments of the disclosure provide an organic light emitting display panel, including the above-described array substrate.

In technical solutions provided in the disclosure, an array substrate includes a plurality of pixel units arranged in a plurality of rows and a plurality of columns and divided into a plurality of pixel unit groups each including n rows of pixel units, where n is equal to or larger than 1. Moreover, a driving circuit is disposed for each pixel unit group on a side of the pixel unit group in the row direction, and the driving circuit interleaves with neighboring preceding and succeeding pixel unit groups in a column direction of the pixel units. Accordingly, the driving circuits are hidden among the pixel units through interleaving of the driving circuits with the neighboring preceding and succeeding pixel units in the column direction of the pixel units on the array substrate, that is, the display area interlaces with the peripheral circuit area, instead of separately disposing the driving circuits outside the display area formed by the pixel units. As such, displaying is performed on the entire area of the display panel during operation to achieve a frameless display effect.

DETAILED DESCRIPTION

The disclosure will be further described in detail in conjunction with the accompanying drawings and the embodiments of the disclosure. It can be understood that the embodiments described here are not intended to limit the scope of the disclosure but intended to explain the disclosure, and embodiments described here show merely a portion of but not all of the embodiments of the disclosure.

The following technical solutions are proposed to avoid a frame surrounding a display panel in the related art, to solve the problem of a frameless display panel.

FIG. 2 is a schematic top view of a first array substrate, according to embodiments of the disclosure. As shown in FIG. 2, the array substrate includes a plurality of pixel units 21 arranged in a plurality of rows and a plurality of columns, and the plurality of pixel units 21 are divided into a plurality of pixel unit groups each including n rows of pixel units, where n is larger than or equal to 1, and n is equal to 1 in the embodiments shown in FIG. 2. The array substrate further includes at least one driving circuit 22 each disposed on a left side or a right side of the pixel unit group in the row direction. The driving circuits 22 interleave with neighboring preceding and succeeding pixel unit groups thereof in a column direction of the plurality of pixel units 21.

The interleaving arrangement in embodiments of the disclosure refers to that: on the basis of arranging the pixel units in rows and grouping a plurality of rows of the pixel units into a pixel unit group, one or more of the rows of pixel units in each pixel unit group are extended to a frame area, and an area for disposing a driving circuit is reserved at a left or right side (in a row direction) of an unextended row of the pixel units in the pixel unit group, so that the driving circuit is hidden among the pixel units, as such, on a left side edge or a right side edge of the display area constituted by the pixel units, the peripheral circuit area including the driving circuits and the display area are presented alternately, instead of separately disposing the peripheral circuit area outside the display area constituted by the pixel units. That is, the display area interlaces with the peripheral circuit area in which the driving circuits are disposed, as a result, displaying on the entire area of the display panel in operation is possible, to achieve a frameless display effect. FIG. 3 is a schematic view of a display effect of the display panel shown in FIG. 2. As shown in FIG. 3, on a left side edge of the display area 11, the peripheral circuit area 12 constituted by driving circuits are presented alternately with the display area 11. With the increase of a resolution of the display panel, a display effect difference at the left side becomes less and less significant until unidentifiable by human's eyes, thereby achieving a frameless display panel.

FIG. 2 shows a case in which each pixel unit group is constituted by one row of pixel units. Additionally, other cases in which each pixel unit group is constituted by two, three or more rows of pixel units will be further described below in subsequent embodiments of the disclosure.

In embodiments of the disclosure, each row of pixel units is driven by a driving circuit. The driving circuit may include n cascaded shift register units each configured to drive one row of pixel units. That is, the shift register units correspond to the rows of pixel units in a one-to-one corresponding relation. If each pixel unit group includes n rows of pixel units, n cascaded shift register units are included in the driving circuit and configured to successively drive the n rows of pixel units in a preset sequence.

A technical solution in which each row of pixel units is provided with a corresponding shift register unit can be implemented in two manners. A first one of the two implementation manners is to arrange a corresponding shift register unit at one side of each row of pixel units within the pixel unit group, in this case, shift register units for neighboring pixel unit groups are required to be disposed at different sides to achieve the interleaving arrangement of the driving circuits with the neighboring preceding and succeeding pixel unit groups. This first implementation manner is suitable for cases in which each pixel unit group includes one, two, three or more rows of pixel units, that is, n=1, 2, 3, and so on. A second one of the two implementation manners is to arrange shift register units corresponding to the respective rows of pixel units in each pixel unit group at one side of one of the rows of pixel units within the pixel unit group, in this case, the shift register units for neighboring pixel unit groups may be disposed either at the same side or at different sides to achieve the interleaving arrangement of the driving circuits with the neighboring preceding and succeeding pixel unit groups. This second implementation manner is suitable for cases in which each pixel unit group includes two or more rows of pixel units, that is, n=2, 3, and so on. For the case in which n>3, the shift register unit may be disposed at a row of pixel units other than the first and last rows of pixel units.

It should be noted that, in FIGS. 4A to 7D illustrating subsequent embodiments of the disclosure, for ease of description, a plurality of pixel units 21 at the same row are not identified individually. However, it can be understood by those skilled in the art that the pixel units in each row may include a plurality of individual pixel units 21.

For the above first implementation manner, FIG. 4A is a schematic top view of an array substrate where n equals 1, according to embodiments of the disclosure. As shown in FIG. 4A, in embodiments, each pixel unit group includes one row of pixel units 21, and accordingly each driving circuit 22 includes one shift register unit 23. Thus, a corresponding shift register unit 23 is disposed at one side of each row of pixel units 21, and shift register units 23 for any two neighboring rows of pixel units are disposed at different sides. Meanwhile, in embodiments, the shift register units 23 at the same side can be cascaded in sequence in a column direction, to form two columns of shift register units 23 disposed on a left side and a right side of the pixel units 21, respectively. In operation, the shift register units successively control the respective rows of pixel units in sequence according to a time sequence control signal.

FIG. 4B is a schematic top view of the first array substrate where n equals 2, according to embodiments of the disclosure. As shown in FIG. 4B, in embodiments, each pixel unit group includes two rows of pixel units 21, and accordingly each driving circuit 22 includes two shift register units 23. In embodiments, a corresponding shift register unit 23 is disposed at one side of each row of pixel units 21 within each pixel unit group, and shift register units 23 for neighboring pixel unit groups are disposed at different sides, that is, the shift register units 23 for a pixel unit group are disposed at a side, while the shift register units 23 for a neighboring pixel unit group are disposed at the opposite side. Meanwhile, in embodiments, the shift register units 23 at the same side can be cascaded in sequence in the column direction, to form two columns of shift register units 23 disposed on a left side and a right side of the pixel units 21, respectively. The shift register unit 23 for the first row of pixel units within each pixel unit group is connected to a shift register unit 23 for the second row of pixel units within the second preceding pixel unit group, if any, and the shift register unit 23 for the second row of pixel units within said each pixel unit group is connected to a shift register unit 23 for the first row of pixel units within the second succeeding pixel unit group, if any. In operation, the shift register units successively control the respective rows of pixel units in sequence according to a time sequence control signal.

FIG. 4C is a schematic top view of the first array substrate where n equals 3, according to embodiments of the disclosure. As shown in FIG. 4C, in embodiments, each pixel unit group includes three rows of pixel units 21, and accordingly each driving circuit 22 includes three shift register units 23. In embodiments, a corresponding shift register unit 23 is disposed at one side of each row of pixel units 21 within each pixel unit group, and shift register units 23 for neighboring pixel unit groups are disposed at different sides. Meanwhile, in embodiments, the shift register units 23 at the same side can be cascaded in sequence in the column direction, to form two columns of shift register units 23 disposed on the left side and the right side of the pixel units 21, respectively. The shift register unit 23 for the first row of pixel units within each pixel unit group is connected to a shift register unit 23 for the third row of pixel units within the second preceding pixel unit group, if any, and the shift register unit 23 for the third row of pixel units within said each pixel unit is connected to a shift register unit 23 for the first row of pixel units in the second succeeding pixel unit group, if any. In operation, the shift register units successively control the respective rows of pixel units in sequence according to a time sequence control signal.

For the above second implementation manner, FIG. 5A is a schematic top view of a second array substrate where n equals 2, according to embodiments of the disclosure. As shown in FIG. 5A, in embodiments, each pixel unit group includes two rows of pixel units 21, and accordingly each driving circuit 22 includes two shift register units 23. In embodiments, the two shift register units 23 are both disposed at one side of the first row of pixel units within each pixel unit group, and the shift register units 23 for neighboring pixel unit groups are disposed at different sides of the pixel units 21. Meanwhile, in embodiments, the shift register units 23 at the same side can be cascaded in sequence in the column direction to form two columns of shift register units 23 disposed on the left side and the right side of the pixel units 21, respectively. The shift register unit 23 for the first row of pixel units within each pixel unit group is connected to a shift register unit 23 for the second row of pixel units in the second preceding pixel unit group, if any, and the shift register unit 23 for the second row of pixel units within said each pixel unit group is connected to a shift register unit 23 for the first row of pixel units in the second succeeding pixel unit group, if any.

These embodiments are different from the embodiments of FIG. 5A in that the shift register units 23 for neighboring pixel unit groups are disposed at the same side, where an interleaving arrangement of the driving circuits with the pixel unit groups is likewise achieved. The shift register units 23 at the same side are cascaded in sequence in the column direction to form one column of shift register units 23 on the right side of pixel units 21, that is, the shift register unit 23 for the first row of pixel units within each pixel unit group is connected to a shift register unit 23 for the second row of pixel units in the immediately preceding pixel unit group, if any, and the shift register unit 23 for the second row of pixel units 21 within said each pixel unit group is connected to a shift register unit 23 for the first row of pixel units in the immediately succeeding pixel unit group, if any. In operation, the shift register units successively controls the respective rows of pixel units in sequence according to a time sequence control signal. As shown in FIG. 5B, both of the two shift register units within each pixel group are disposed at one side of the first row of pixel units in the pixel unit group, or alternatively, in some embodiments, both of the two shift register units can be disposed at one side of the second row of pixel units in the pixel unit group. Although the shift register units are shown in FIG. 5B to be disposed at the right side, the shift register units can be disposed alternatively at the left side.

FIG. 5C is a schematic top view of the second array substrate where n equals 3, according to embodiments of the disclosure. As shown in FIG. 5C, in embodiments, each pixel unit group includes three rows of pixel units 21, and accordingly each driving circuit 22 includes three shift register units 23. In embodiments, the three shift register units in each pixel unit group are all disposed at one side of one row of pixel units within the pixel unit group, and the shift register units 23 for neighboring pixel unit groups are disposed at different sides. Meanwhile, in embodiments, the shift register units 23 at the same side can be cascaded in sequence in the column direction to form two columns of shift register units 23 disposed on the left side and the right side of pixel units 21, respectively. The shift register unit 23 for the second row of pixel units within each pixel unit group is connected to a shift register unit 23 for the third row of pixel units in the second preceding pixel unit group, and the shift register unit 23 for the third row of pixel units within said each pixel unit group is connected to a shift register unit 23 for the second row of pixel units in the second succeeding pixel unit group. In operation, the shift register units successively control the respective rows of pixel units in sequence according to a time sequence control signal. As shown in FIG. 5C, all the three shift register units are disposed at one side of the second row of pixel units in each pixel unit group. In some embodiments, all three shift register units in each pixel unit group can be disposed at one side of the first or third row of pixel units in the pixel unit group.

FIG. 5D is a schematic top view of the third array substrate where n equals 3, according to embodiments of the disclosure. As shown in FIG. 5D, in embodiments, the shift register units 23 for neighboring pixel unit groups are disposed at the same side, and an interleaving arrangement of the driving circuits with the pixel unit groups is achieved as well. Moreover, the shift register units 23 at the same side can be cascaded in sequence in the column direction, to form one column of shift register units 23 disposed on the right side of the pixel units 21, that is, the shift register unit 23 for the second row of pixel units 21 within each pixel unit group is connected to a shift register unit 23 for the third row of pixel units in the immediately preceding pixel unit group, if any, and the shift register unit 23 for the third row of pixel units 21 within said each pixel unit group is connected to the shift register unit 23 for the second row of pixel units in the immediately succeeding pixel unit group, if any. In operation, the shift register units successively control the respective rows of pixel units in sequence according to a time sequence control signal. As shown in FIG. 5D, all the three shift register units within each pixel group are disposed at one side of the second row of pixel units in the pixel unit group. In some embodiments, all three shift register units within each pixel group can be disposed at one side of the first or third row of pixel units in the pixel unit group. Although the shift register units are shown in FIG. 5D to be disposed at the right side, the shift register units can be disposed alternatively at the left side.

Unlike the above-described solution in which each row of pixel units are provided with a corresponding shift register unit, embodiments of the disclosure also provide another technical solution of a driving circuit, where the driving circuit includes one shift register unit and a controlling unit (e.g. a multipath controlling unit or one-to-multiple controlling unit), each row of pixel units within the pixel unit group is connected to the shift register unit via the controlling unit. This implementation manner of the driving circuit is suitable for the case in which each pixel unit group includes two or more rows of pixel units, that is, n is equal to or larger than 2.

The technical solution in which each pixel unit group is provided with a shift register unit through the controlling unit can be implemented in two manners. A first one of the two implementation manners is to provide the driving circuit at one side of each row of pixel units within each pixel unit group, where the driving circuits for neighboring pixel unit groups are disposed at different sides. A second one of the two implementation manners is to provide the driving circuit at one side of one row of pixel units within each pixel unit group, where the driving circuits for neighboring pixel unit groups are disposed at the same side or different sides.

Each shift register unit is connected to a shift register unit in a driving circuit corresponding to the second preceding pixel unit group, if any, and connected to a shift register unit in a driving circuit corresponding to the second succeeding pixel unit group, if any. In operation, the cascaded shift register units receive driving signals in sequence according to a time sequence control signal. Within each pixel unit group, the shift register unit is configured to apply the driving signal to each row of pixel units in the pixel unit group simultaneously through the controlling unit, or alternatively, in some embodiments, apply the driving signal to each row of pixel units in the pixel unit group in sequence in the column direction in a time-division manner.
